Nanomechanics of Networked 2D Materials and Their Hierarchical Structures
DescriptionDue to the outstanding physical properties, two-dimensional (2D) materials beyond graphene, such as single and few-layer molybdenum disulfide (MoS2) and hexagonal boron nitride (h-BN) hold great promise for a variety of novel applications. Recently, networked 2D materials, i.e. hierarchically structured 2D materials in 3D networked scaffolds with characteristic feature sizes from nano to macro, have emerged with increased interests. With the combination of nano-engineering and bio-inspirations, synthetic networked 2D materials hold great potential in a number of structural and functional applications; however, those applications often involve mechanical loadings, which requires comprehensive understanding on their mechanical behavior and structural reliability. So in this project, we aim to investigate the mechanics of networked 2D materials, e.g. M0S2, WSe2and h-BN, based on our multi-scalein situmechanical techniques. Assisted with in situ SEM/TEM techniques and atomistic simulations, we will be quantifying the mechanical responses of 2D material building blocks and modeling their interfaces and cross-linking in their 3D networked scaffolds.
